Conciseness

Mostly efficient with copy-paste commands and brief rationale, but a few explanatory asides ('Local-only migrations cause confusing works locally breaks in production issues') could be trimmed; sits above the 3 anchor but not fully lean enough for 5.

Actionability

Fully executable guidance throughout — concrete `pnpm`/`wrangler` commands, copy-paste SQL fixes, and a complete TypeScript batching example covering the common cases, matching the 5 anchor.

Workflow Clarity

The five-step flow is clearly sequenced with an explicit Verify checkpoint (PRAGMA table_info for both local and remote), plus a diagnosis→fix feedback loop for stuck migrations and batching guidance for the destructive/batch case, matching the 5 anchor and satisfying the validation requirement.

Progressive Disclosure

Well-organized with clear section headers and cohesive single-file content that legitimately belongs together with no nested references, but it is a monolithic file rather than an overview pointing to one-level-deep references, fitting the 4 anchor.

Specificity

Lists multiple concrete actions — 'generate with Drizzle, inspect SQL for gotchas, apply to local and remote, fix stuck migrations, handle partial failures' — giving comprehensive coverage of the migration workflow, matching the 5 anchor.

Completeness

Explicitly answers both 'what' (the five workflow actions) and 'when' ('Use when running migrations, fixing migration errors, or setting up D1 schemas') with concrete trigger phrases, matching the 5 anchor.

Trigger Term Quality

Includes natural phrases users would say ('running migrations', 'fixing migration errors', 'setting up D1 schemas') with good coverage, but misses common synonyms like 'drizzle migrations' or file-extension triggers, fitting the 4 anchor above the 3.

Distinctiveness Conflict Risk

Targets a clear niche — Cloudflare D1 with Drizzle ORM — with distinct triggers and minimal overlap risk with other skills, matching the 5 anchor.
